Question

If the current in a wire which is placed perpendicular to a magnetic field increases the force on the wire

Answer 1

The force on the wire increases

Step-by-step explanation:

Since the force on the wire F = BILsinФ where B = magnetic field strength, I = current in wire, L= length of wire and Ф = angle between the magnetic field and the wire.

Given that the magnetic field and the wire are perpendicular, Ф = 90°

So, F = BILsin90° = BIL

Since B and L are constant, F ∝ I

So, if the current in the wire increases, the force on the wire also increases.
